Google apologises for human error that labelled all search results as harmful

Google has named 'human error' as the cause of technical problems that saw all search results labelled as harmful for a period at the weekend.

Google has blamed 'human error' for technical problems that left users believing they were unable to safely access search results at the weekend.

For more than half an hour on Saturday, every search result was accompanied by the message: "This site may harm your computer".

Google normally flags search results with the message if the site is known to install malicious software in the background.

However, "human error" in a Saturday update of the risky sites list caused all sites to be flagged, instead of only those sites identified by non-profit organisation, according to a Google blog posting.

Marissa Mayer, vice president search products and user experience at Google apologised to search users for the inconvenience and to site owners whose pages were incorrectly labelled.

"We will carefully investigate this incident and put more robust file checks in place to prevent it from happening again," said Mayer.
